Kei te whakahaerehia te umanga haurua-ira i ngā rohe ā-tinana o ngā mea ka taea te ine me te hanga. Kei roto i ngā ara iahiko whakauru hou ngā transistors he roa kuaha kei raro iho i te 3 nanometer — he inenga kei reira te ngota silicon kotahi e tohu ana i te wāhanga nui o te rahi āhuatanga matua. Ko ngā pūnaha lithography, ngā taputapu tirotiro wafer, me ngā taputapu ine e hanga ana me te manatoko i ēnei hanganga me whakatutuki i te tika o te tūnga, te wehenga wiri, me te pumau o ngā inenga e ahua kore e taea i ngā tau rua tekau ki muri.
Heoi, i roto i ēnei rūma e kī ana i ngā hangarau whakamiharo, ko tētahi o ngā rauemi hanganga tino nui ko tētahi mea tawhito: ko te karāneti. Ko te karāneti pango kua oti te mīhini me te whakahaere i te wera te hanga i te poutokomanawa hanganga o te nuinga o ngā papaaho taputapu haurua-ā-ira tino matatau o te ao. Mā te mārama ki te take - me te take kāore i te ōrite ngā karāneti katoa - ka whakamārama i tētahi āhuatanga nui, ā, he maha ngā wā ka warewarehia o te hangarau taputapu haurua-ā-ira.
Te Taiao Taputapu Ārahi-Haumaru: Ngā Mea e Ora ai te Pūtake
Ka whakahaerehia he pūnaha whakaaturanga whakaahua-ipurangi (matawai, taputapu hiko rānei) i roto i tētahi taiao rūma ma, ka whakahaeretia te maha o ngā matūriki e rere ana i te hau ki ngā taumata Akomanga 1, Akomanga 10 rānei — arā, he iti iho i te 1, 10 rānei ngā matūriki mō ia putu kūpiko o te hau i te 0.5 μm, nui ake rānei. Me tutuki i te taputapu tonu te āheinga ki te tūnga atamira i raro i te 1 nanometer, te tika o te paparua i raro i te 2 nanometer, me te ōrite o te arotahi puta noa i tētahi anga 300 mm i roto i ētahi nanometer.
Ko te atamira wafer e whakatutuki ana i tēnei ka neke i ngā tere neke atu i te 1 mita ia hekona, ka whakateretere, ka whakaroa hoki i ngā tere neke atu i te 10 karamu, ā, ka tāruatia tēnei huringa i ngā mano tini wā ia hāora — i ia hāora, i ia rā, mō ngā tau. Kaua te turanga granite e tautoko ana i tēnei atamira e piko, e ngokingoki, e haruru rānei i ngā huarahi e kino ai te ine i te tūranga o te atamira. Me noho pumau tonu te āhua puta noa i te awhe mahi wera o te taputapu. Ā, me mahi pono e ia ēnei mea katoa mō te roanga o te oranga mahi o te pūnaha, tera pea he tekau tau, neke atu rānei.
Ehara ēnei i te āhua mahi ngāwari. He nui rawa ngā tono mō ngā wāhanga katoa — tae atu ki te turanga kerēmete āhua kore mahi.
Te Wehewehe me te Whakaiti i te Wiri: Te Painga Tinana o te Granite
He nui te haumi a ngā whare hiko hiko ki te wehewehe wiri - mai i ngā turanga whare (ka taea te whakairi ki runga i ngā rarangi o ngā whakawehe hau) ki ngā pūnaha whakakore wiri hohe taumata-taputapu. Engari he rohe kei ēnei pūnaha. Kāore e taea e rātou te whakakore i ngā wiri katoa, ā, kāore e taea e rātou te urupare wawe ki ngā auau katoa. Ko te turanga mīhini karāhe te wāhanga whakamutunga o te wehewehe wiri.
Ko te ahupūngao o te whakaiti wiri e pai ake ana ki ngā rauemi he nui te papatipu me te kaha whakaiti motuhake. Ko te kirikiri pango matotoru - me tōna hanganga moroiti tioata o te quartz, te feldspar, me te mika e honoa ana - e whakarato ana i te whakaiti ā-roto pai o ngā wiri ā-pūkaha mā te whakakotahitanga o ngā pānga papatipu me te waku rohe witi. Ko ngā wiri e tomo ana ki te turanga mā te papa, mā roto rānei i ngā kaha tauhohenga o te atamira neke ka mimitihia, ka mararahia i roto i te kirikiri i mua i te horapa atu ki ngā pūnaha ine tairongo.
Ahakoa te kaha kume o te maitai, he pai ake te mahi a te karāneti i te maitai i tēnei āhuatanga. Ko te take kei roto i te hanganga moroiti tioata: ka marara, ka mimiti hoki te hanganga witi polycrystalline o te karāneti i te kaha wiri i ngā rohe witi, engari ko te hanganga tioata kua whakaritea o te maitai ka pai ake te whakahaere i te wiri. He pai ake te rino maka i te maitai mō te whakamātao, koia te take i whakamahia ai mō ngā turanga taputapu mīhini tino tika - engari he pai ake te karāneti tino tika.
Te Pūmautanga o te Wera: Te Pūtake o te Ahuatanga o te Nanomita
I te tauine nanometer, ko te pumau wera te mea matua e whakahaere ana i te auautanga o ngā āhuatanga. Ko te huringa pāmahana 1°C i roto i te wāhanga maitai 1-mita ka puta he 11.7 maikiromita o te whakawhānui wera - 11,700 nanometer. I roto i te karāhe, ko te whakawhānui ōrite he 6–8 maikiromita, tata ki te haurua o te maitai. I roto i ngā uku karāhe whakawhānui tino iti (pēnei i a Zerodur, ULE rānei), he 0–0.02 maikiromita noa iho ia nekehanga - engari he nui ake te utu o ēnei rauemi, ā, he uaua ki te tukatuka i roto i ngā rahi nui e hiahiatia ana mō ngā turanga mīhini.
Mō ngā turanga taputapu haurua-ira, me iti noa te whanonga whakawhanui wera o te karāhe, engari me matapaetia anō hoki. Ka whakamahia e ngā kaihoahoa te CTE e mōhiotia ana o te karāhe hei hanga i te utu wera ki roto i te atamira.pūnaha ine tūranga. Ko te CTE kāore e taea te matapae, te rerekē rānei i te wāhi — ka puta pea i roto i te kirikiri kounga iti, i te kirikiri kua tīpakohia hē rānei — ka kore e taea te whakatika, ā, ka hua ake ngā hapa tūranga e pā ana ki te pāmahana kāore e taea te whakatikatika.
Koinei tētahi o ngā take he aha te hiranga o te pūtake me te whakatakotoranga motuhake o te karāhe i roto i ngā tono taputapu haurua-ira. Me whakaahua te rauemi mō te whanonga wera - kaua e tohua whānuitia ko te "karahe pango" - ā, me tutuki hoki ngā whakaritenga kiato me te ōritetanga e whakarite ana kia ōrite te whanonga wera puta noa i te wāhanga.
Ngā Mata Karāhe Āhua Hau: Te Atanga Nekehanga
He maha ngā pūnaha nekehanga taputapu haurua-haurua e whakamahi ana i ngā peera hau — he kiriata angiangi o te hau pēhanga e āhei ai ngā wāhanga ki te neke i runga i te mata tohutoro me te kore waku me te kore kakahu pa. Ka tukuna e ngā peera hau he maeneene nekehanga iti-nanometer, kāore he whanonga paheke-piri (ka kino te tūnga o te tauine nanometer), ā, kāore he poke hinu e kino ai te taiao rūma ma.
He tino whakawhirinaki te mahi a te peera hau ki te mata e eke ana. Ka huri ngā hapa papatahi o te mata peera hei hapa tūnga atamira. Ka pā te taratara o te mata ki te pumau o te kiriata hau. Me mārō te rauemi kia ātete ki te pakaru mēnā ka hinga te kiriata hau mō tētahi wā poto i te wā e whakamahia ana. Ā, me hototahi te rauemi ki te atamira me te pūnaha tuku hau kia kore ai e rerekē te whānui e whakarerekē ana i te āputa hau.
Ko te karāneti tino tika, he mea pania kia papatahi ake i te 1 μm i runga i te tawhiti haere o te peera, ā, he mea oro ki te Ra i raro iho i te 0.1 μm, ka tutuki i ēnei whakaritenga katoa. Ko te whakakotahitanga o te pakeke teitei (te ātete ki te kakahu), te taratara iti o te mata (e tautoko ana i ngā kiriata hau pumau), me te pumau o ngā āhuatanga (e pupuri ana i te papatahi i roto i te wā) ka waiho te karāneti hei rauemi whiriwhiri mō ngā mata tohutoro peera hau i roto i ngā tono semiconductor uaua.
Ngā Taputapu Tirotiro me te Ine i te Granite i roto i te Wafer
Haunga te mahi whakairo, he rite tonu te hiranga o te karāhe i roto i te huinga taputapu e whakamahia ana hei tirotiro me te ine i ngā papa haurua-haurua. Ko ngā karu hiko matawai (SEM), ngā pūnaha hihi katote arotahi (FIB), ngā taputapu tirotiro hapa whatu, me ngā pūnaha inenga paparua katoa e whakawhirinaki ana ki ngā turanga pumau, kore wiri hei whakatutuki i te tika o te ine e hiahiatia ana.
Me whakaahua te karu hiko matawai irahiko (CD-SEM) i te whānui o te kuaha o te 3 nanometer me te tika o te whakaahua. Ko te wiri i waenga i te tauira me te hihi irahiko i te wā e kohia ana te whakaahua ka pōuriuri i te whakaahua, ā, ka puta he koretake o te ine. Ka wehea te wāhanga tauira e te turanga karāhe i ngā wiri o te papa, ka whakarato i te taiao miihini marino e taea ai te ine i te tauine ngota.
Waihoki, ka whakamahia e ngā pūnaha ine marara whatu me ngā taputapu āhuahanga wafer ngā turanga karāhe me ngā mata tohutoro hei pupuri i ngā whanaungatanga āhuahanga i waenga i ngā hihi ine me te mata wafer. Ko te tika o te ine o te taputapu katoa — e whakatau ana mēnā ka paahitia, ka kore rānei he tirotiro a te wafer — ka whakawhirinaki ki te pumau o te āhuahanga o te karāhe i raro iho.
Ngā Whakamahinga Ahumahi: He Mahere Wāhanga o te Granite i roto i te Hanganga Semiconductor
Hei mārama ki te whānuitanga o te mahi a te karāhe i roto i te hanga haurua-ira, whakaarohia ngā momo taputapu e kitea pinepine ana ngā wāhanga karāhe tino tika: ngā matawai whakaahua me ngā taputapu hiko (ngā turanga atamira wafer, ngā turanga atamira reticle, ngā anga tohutoro); ngā taputapu whakamahere matū miihini (CMP) (ngā mata tohutoro kōpae whakatikatika, ngā wāhanga ine); ngā pūnaha tirotiro wafer (ngā turanga atamira, ngā whakaata tohutoro, ngā papaaho wehe wiri); ngā taputapu ine tae atu ki ngā ine marara, ngā ine ellipsometer, me ngā taputapu paparua interferometric; ngā pūnaha whakahaere me te kawe wafer e ārai ana te pumau o te taha i te kino o te wafer; ngā pūnaha tirotiro hihi irahiko me te ine; me ngā taputapu whakauru katote e tino hira ana te pumau o te tūnga hihi.
I roto i ia o ēnei whakamahinga, ehara te karāhe i te whakaurunga taonga engari he wāhanga tino tika e whakatau tika ana i te kaha o te pūnaha e te whakatakotoranga mahi. Ko te rerekētanga i waenga i te wāhanga karāhe i hangaia ki te papatahi ±10 μm me te mea i hangaia ki te papatahi ±0.5 μm ehara i te whakapainga 20× — tera pea ko te rerekētanga i waenga i te taputapu e tutuki ana i tana whakatakotoranga me te mea kāore e taea.
Te Kimi i te Granite Tika mō ngā Whakamahinga Ārahi-Haumaru
I runga i ngā whakaritenga mahi o ngā tono haurua-ā-ira, he whakatau hangarau nui te whiriwhiri me te tohu i tētahi kaiwhakarato karāhe. Haunga ngā whakatakotoranga rauemi taketake — te kiato, te tauwehenga whānui wera, te taumata papatahi — me aromatawai ngā kaihoko i te kaha ine tuturu a te kaiwhakarato (ka taea e rātou te manatoko i tā rātou e kī nei ka tutuki?), ō rātou wheako ki ngā tono taputapu haurua-ā-ira, te pakari o tā rātou pūnaha whakahaere kounga, me tō rātou kaha ki te pupuri i te ōritetanga puta noa i ngā puranga whakaputa.
He uaua te mekameka tuku o te umanga haurua-ira: ka taea e te wāhanga tino tika te kore e tutuki i ngā whakaritenga te whakaroa i te tuku taputapu, te pirau i ngā raraunga whakaputa, te hiahia rānei kia nui te utu mō ngā whakahoutanga mara. He iti noa te utu o te turanga karāhe tino tika e tutuki ana i ngā whakaritenga ki te whakataurite ki te utu o te mea kāore e tutuki.
Whakamutunga
Kāore e kitea te tūranga o te karāneti i roto i ngā taputapu haurua-ira ki te nuinga o ngā kaimātakitaki — e huna ana i raro i ngā hangarau ataahua ake o ngā taiaho, ngā hihi irahiko, me ngā whatu nano. Engari he mea nui. Ko te tika me te auau o ngā taputapu hanga haurua-ira e whakawhirinaki ana ki te pumau o ngā āhuatanga, te whakaiti i te wiri, me te kounga o te mata o ngā wāhanga karāneti tino tika.
I te mea kei te haere tonu te ahumahi haurua-ira ki te pana i ngā rahinga transistor ki raro i ngā rohe o ia au, ka piki haere tonu ngā tono mō ia wāhanga o ngā taputapu — tae atu ki te turanga karāhe. Ko ngā kaihanga e taea te whakarato i ngā wāhanga karāhe e tutuki ana i ēnei whakaritenga e whanake haere ana, me ngā raraunga ine kua manatokohia hei whakamatau, ka whai wāhi nui ki te whakahohe i te whakatupuranga hou o te hangarau haurua-ira.
